1994 toyota land cruiser fuel pump, bad gas or fuel filte??? Motor quits then starts up again... whats up?? Thank you, mike

Is the fuel contaminated possibly, is the fuel pressure low? If the answer is no to both questions I would lean towards the idle air motor especially if idling is the only issue. Other than idling does it run well?

Tune up on it. Could be a bad fuel pump our filter.

You may have a frozen cable to the actuator, or the actuator itself may be bad. Check also for vacuum leak(s). Peace. God bless.

sorry no idea without a good look myself ,could be anything giving this problem

sounds like the fuel pump or regulator issue. fuel is draining back to the tank. try turning the ignition on and off 3 times without cranking the engine, then try to start it. If that works, replace the pump assembly, filter and regulator. airtex or delphi makes a great replacement alternative to an actual toyota part, and is much less money. Happy Motoring.

Could be bad compression or a weak fuel pump, but I'd check the fuel filter first especially if you've run out of gas recently.

check fuel pressure.

check glow plugs and timer...Make sure you have voltage at the glow plugs...

What exactly is it doing. First of all for starters, did you put any Stabul in the fuel tank. Its an aditive to prevent the fuel from going bad.

Gas usually goes bad if the car sits for long amounts of time without running.

I would add some stable and a couple fresh galons of gas to it and turn the key to the on position to allow the fuel pump to pump fuel up the lines before starting.

Sitting for a long time, gas can seperate and you may have water pooling at the bottom or corosion or deposits in the tank and fuel filter.

The Landcruiser 1HD engine uses 9.3 liters of oil with the filter. The oil is replaced every 5000Kms.
